To answer your question, Category Element Part seems correct, but I think
that Part is already a Piece, by your nomenclature. I guess the proper BrickLink
way would be Category Item (for a certain item) and then maybe Piece for an
Item in specific color. Maybe you should also introduce "Mold" into the database,
because--as you probably know--some of the old items used to look quite
different.
But my most important point is: if you're adding all your pieces to a database,
why not add them to BrickLink inventory? Even better, you can try Rebrickable,
which will give you a lot of interesting options when looking into completing
sets.

Soviet, thank-you for the information and assistance. I will be sending you
a personal message with a picture of my SIPs and my many containers of unassigned
pieces.
The issue of mould differences and older pieces general is a concern. I try
to keep my SIPs period correct. I have separate containers for older pieces
where the PIP marks are on the side rather than in the middle of one of the studs
as is the case I do use BL to manage my SIPS. Currently I have 358 Wanted Lists,
one per SIP. I had considered using BL's Inventory feature to manage my
unassigned pieces, however, that is only available to Sellers members, not to
Buyers. Therefore, I'm using this project as a learning opportunity to develop
a DB with a web interface. Programming is my other passion.
Regards, Mark

| | Hi all.
BACKGROUND: Let my start by saying that unlike my grandchildren, Marcus and
Soren, I am not a "Master Builder". I am a "Master Collector." My brick hobby
is to purchase long forgotten brick collections from parents of teen + former
brick fan that have been collecting dust in the basement or attic for years.
Once in my possession, I discard the fake pieces, wash the real ones then sort
them out looking for the special pieces that will tell me which sets the original
owner possessed.Then I try to re-assemble those sets.
PROBLEM: Currently, I have about 330 sets that I have identified as previously
owned. Those are my SIPs, "sets-in-progress." Each SIP has a container where
I store the parts that I've located. Together those 330 SIPs consist of
approximately 56,000 pieces. Of those, I have located about 23,000 pieces and
I am still looking for the other 23,000 pieces. I would guess my personal brick
collection consists of 100,000+ pieces that are not currently assigned to a SIP.
They are sorted and stored in other many other containers. When I need to locate
a piece for a SIP I look in about 5 "likely" containers then give up. Do I not
have the piece or is just in one of the many many "unlikely" containers?
SOLUTION: I'm building a MySQL Database to keep track of my collection.
Using BL's category system, there exist many bricks, slopes, arches etc.,
based more or less on shape. Within the sub-category bricks there are 1x1,
2x2, 2x4 etc., more or less based on size.
QUESTIONS: Q1;What are these sub-categories called? I would call them an ELEMENT.
is that correct? is there a better name for the sub-categories? Further, the
sub-categories such as 1x1 bricks of course come in many colours. Q2: What are
these sub-sub-categories called, or what are these ELEMENTs with a particular
colour called? I would call them a PART. Correct? Any other better name?
Q3; Lastly, if I hold in my hand, one blue 1x1 brick, what should that be called?
I would suggest that is a PIECE. Correct? Any better answer?
CATEGORY :: ELEMENT :: PART :: PIECE ??

First, that you have trouble finding names for your entities is a big clue they
are the wrong entities.
Vocabulary-wise, “element,” ”part” and “piece” are mostly the same thing.
LEGO uses “design” for the mould (and decor  ) and “element” for design + colour.
LEGO’s “DesignID” is the number most often used by BL, LDraw and others as a
“part ID” or “name” (the text explaining the part is then a “description”).
And LEGO’s “ElementID,” the 6-digit number that appears in their instructions,
is what BL calls a PCC / Part-Colour-Code.
So, you found out that BL’s categories are “more or less based on shape.” That
means they aren’t.
Then you thought about colours. “Everybody knows” you don’t sort LEGO by colour
 
Then you found that many pieces share the same shape and are distinguished by
their size. Not all are.
So, what are you trying to do with this? Are you are trying to categorize your
parts to fit them in containers?
Then what you found out is that parts have attributes: general shape, size, colour,
and you “more or less” ordered them: shape first, then colour, then size.
Okay, that’s some sort of sieve system to define containers.
But why do you need to put that in you DB?
You have a list of parts of one side, your inventory, and lists of parts on the
other side, the wanted parts for the sets.
How will the database be used? You need to know first if the exact part (ID
+ colour) is in your inventory and, second, where it’s stored if it is.
Where do this categorization of yours is used in the DB?
Nowhere that I see.
Or do you want to have an algorithm that takes a BL part (ID + description +
colour) and turns out a container number?
But does it have to be in the DB? Not that I see.
So I don’t see a need to complicate your DB. You just need to have four main
tables: parts (BL id + description), colours, inventories (list of parts in a
given colour and in a given quantity), and containers (association between a
location and parts).
Besides, you’ll quickly find all “shapes” don’t divise regularly (or at all)
into “colours” or “sizes” (most of the heads are yellow; slopes first divise
by angle, not size; Technic connectors don’t come in many colours nor sizes; etc.).
Especially if you use BL categories as “shapes.”
On this note, here’s a rough categorization that some sellers (who sort many
parts) use as a first sieve:
Bricks & Arches
Brick Modified & Round
Plate
Plate Modified & Round
Slope
Technic
Tile & Panel
Minifig
Other
They are about the same size in a “standard” collection. This might help you
devise your containers’ organization.

It is the other way around. A 1x1 brick is a part. A 1x1 brick in blue is an
element. A single piece in your hand can be called piece or part or element,
whatever you want really.
